7.1.2 Basic Data Exchange Process
The master has to send an software command to start an read or write process of the reader.
After doing all the necessary work at the readers site, the result of the reading or writing proc-
ess or an failure code is sent back to the master.
If there is used an read/write transponder, only the serial number of the transponder will be
read if the basic read command „Get Tag“ („GT <CR>“) is applied.
The data exchange of the whole memory can only be done, if the reader is set to the Mode 2 (
„selective Read (RD) “ and „write (WD)“).
7.1.3 ReadOnly-Transponder
• Start the reader with the command GT (plus <CR>)
• Wait for the answer( max. time to wait is given by the value of TOR Parameter)
• Analyse the received answer:10 characters plus <CR>
The reading result may also been judged according the LED’s.
• LED L2 lit, if there was a successful read.
• LED L3 lit, if there was a No Read.
7.1.4 R / W –Transponder
7.1.4.1 Standard Read Process / Serial Number of the Transponder GT
• Start the reader with the command GT (plus <CR>)
• Wait for the answer( max. time to wait is given by the value of TOR Parameter)
• Analyse the received answer: 8 characters plus <CR>
The reading result may also been judged according the LED’s.
